Buying power banks: What you should look out for
Powerbanks have become an integral part of our everyday lives. They ensure that our smartphones, tablets and other devices are always ready for use – whether we are on the go, traveling or on longer outdoor activities. However, the range of power banks is huge and not every model is suitable for every need. In this blog post, we’ll show you what you should look out for when buying a power bank to find the perfect model for you.
Capacity: How much power do you need?
The capacity of a power bank is given in milliampere hours (mAh) and provides information on how often you can charge your device.
- Small power banks (up to 5,000 mAh): Ideal for occasional emergencies, such as charging your smartphone up to once. Perfect for everyday use and easy to transport.
- Medium power banks (10,000-20,000 mAh): Well suited for frequent users and traveling. They charge smartphones several times or even larger devices such as tablets.
- Large power banks (over 20,000 mAh): These models are ideal for longer trips or charging multiple devices. They are particularly suitable if you want to use laptops or other power-intensive devices at the same time.
Think about how many devices you want to charge and how often you want to use the power bank.
Charging speed: fast and efficient
A power bank should not only store a lot of energy, but also be able to release it quickly. Pay attention to the following features:
- Output power (watts): Fast charging functions such as Quick Charge or Power Delivery (PD) enable your smartphone to be fully operational again in the shortest possible time. An output of at least 18 watts is recommended for fast charging.
- Number of connections: Several USB ports or a mix of USB-A and USB-C are practical if you want to charge several devices at the same time.
Weight and size: Mobility counts
The size and weight of the power bank often depend on its capacity. High-capacity models are heavier and larger, while small power banks are particularly compact. Think about whether mobility is more important to you or whether you would prefer to take more energy with you.
Quality and safety
A good power bank protects your devices from overcharging, short circuits and overheating. Look out for the following features:
- Certifications: Test seals such as CE or RoHS are an indicator of tested quality.
- Protection mechanisms: Functions such as overvoltage protection and temperature sensors are essential to charge your devices safely.
Price-performance ratio
Powerbanks are available in different price ranges – from affordable entry-level models to premium devices. A higher price often means better materials, more features and longer durability. Think about how much you want to invest and compare the models in terms of their features.
Additional functions: More than just energy
Some power banks offer practical extras that make them even more versatile:
- Wireless charging: perfect for wireless charging of compatible devices.
- Solar cells: Useful for outdoor activities when there is no power outlet nearby.
- LED display: Shows you the charging status of the power bank.
Conclusion: The right power bank for your needs
The purchase of a power bank depends on your individual requirements. Before buying, think about how often and what you want to use the power bank for. Pay attention to capacity, charging speed and safety features to make the best choice. With the right power bank, you’ll always be well equipped when you’re out and about and won’t have to worry about empty batteries.
Everything you need to know about power banks
1. what is a powerbank?
A power bank is a portable battery that you can use to charge your electronic devices such as smartphones, tablets, laptops or smartwatches on the go. It serves as an additional energy source when there is no power socket nearby.
A power bank stores electrical energy in an internal battery. This energy is delivered to your device via a USB or Type-C port. To charge the power bank itself, it is connected to a power source via a cable.
The capacity of a power bank is specified in milliampere hours (mAh). Here are a few guide values:
- 5,000 mAh: Suitable for 1-2 smartphone charges.
- 10,000 mAh: Sufficient for approx. 3 smartphone charges or one tablet charge.
- 20,000 mAh or more: Ideal for several devices or laptops.
The charging time depends on the capacity of the power bank and the amperage of the charger. Smaller power banks (e.g. 5,000 mAh) can be charged in 2-3 hours, while larger models (20,000 mAh or more) can take 8-10 hours. Fast charging technologies such as Quick Charge or Power Delivery can shorten the charging time.
Basically yes, as long as the power bank offers the necessary connections and sufficient power. Please note, however:
- Laptops: often require power banks with Power Delivery (PD) and high output power (at least 18-45 watts).
- Devices with fast charging function: Benefit from power banks with Quick Charge or similar standards.
Yes, but there are restrictions:
- Capacity: Powerbanks up to 100 Wh (watt hours) are permitted. For powerbanks between 100-160 Wh, approval from the airline is required.
- Carriage: Powerbanks may only be carried in hand baggage, not in checked baggage.
- Do not overcharge: Disconnect the power bank from the power supply as soon as it is fully charged.
- Avoid extreme temperatures: Store and use your power bank between 10 °C and 35 °C.
- Use regularly: Charge the power bank at least every 3 months to maintain battery life.
High-quality power banks with protective functions (e.g. against overcharging, short-circuiting or overheating) are safe to use. Avoid no-name products or older models without the appropriate safety certificates (e.g. CE, FCC, RoHS).
- Input: The maximum current with which the power bank can be charged (e.g. 5V/2A).
- Output: The maximum amperage the powerbank can deliver to a device (e.g. 5V/3A).
- Pass-Through Charging: Enables simultaneous charging of the power bank and a connected device.
Powerbanks must not be disposed of with household waste. Take them to a collection point for electronic waste or recycling centers. Many electronics stores also offer disposal services.
